Looks like a great photographic excursion,and the chance meeting of a lady that was interested in the whole photography thing too.That's what getting in the field is all about,making things happen!,and its great to see the results.
I am just wondering about the forth shot of lady,its very good.But I am wondering if the use of a light reflector may have made this image better,obviously you did not plan on the possibility of this chance meet up,and from the sound of it had the sea scenes in mind.You did well capturing these images,impromptu as it were.
I bought the light reflector a little while ago,its big,and has silver on one side,and gold on the other-(apparently gold is the colour for skin),and then its outer skin of gold and silver can be taken off and its a sunlight diffuser.You chaps you doubtless have these or seen them.
Its most likely my screen on my old laptop,but It just appears her body is just a tiny bit dark,a reflector held at a distance and walked in to the subject,until the right distance and effect was gauged,may have improved this image?(this is not a critisism)
Great work well done .And I hope to get your thoughts on the suggestion.As I own a 70-200 L F2.8,and this is the 'main menu' type of missions I bought it for.
Cheers Chris
